Passing $navbits[lastelement] variable to FlashVars? Is it possible?

[!!!]

It seems other variables, when inserted into my FlashVars code part correctly get written into the code and thuse passed to the SWF.
However, this variable, although it can be placed anywhere in the HTML code, simply will not be written when I stick it into the FlashVars place.

Is there a way to allow me to pass $navbits[lastelement] into parameters? It would be most helpful, thanks! There are other variables I need to pass into FlashVars as well and if they cannot be written into there then I need to figure it out.

Any suggestions?
Is $navbits[lastelement] only permitted when it will be written on a page, rather than in properties of something?
